Non-expansion bolts are similar to expansion bolts where the head and threads are fixed in a non-conventional manner, the bolt is made of a piece of metal shaft with a conical bore. In other words, these bolts have a threaded end like that of a nut. It does not pass through an opening and does not allow the flow of gas. In other words, it does not expand nor does it contract as it is designed to function.
These bolts are used for a number of purposes such as in automobile repair, electronic equipments, etc. For example, if you need a bolt which can conduct electricity, then you will require a conical shaft with a conical bore. It is possible to differentiate between a non-expansion and a multi-fix bolt by observing that a multi-fix bolt has a conical bore while the bolt which has a conical bore is referred to as a non-expanding bolt. Moreover, a bolt is always a multi-fix bolt when it contains several copper threads which are either side of a conical shaft. Hence, you would always see a number of copper threads surrounding a single core which is a cup-holder.
Apart from these bolts, there exist other varieties such as a concave thread and a convex thread. The concave thread is known to be stronger than the non-expanding variety. Moreover, these types of bolts are preferred when you require a specific conical bore or an expansion bolt is required. It is possible to find these bolts in both flat and conical shape. The flat version is generally used in a large number of applications, while the conical version is used for smaller number of applications such as on valves and seals, in addition to in automobiles.
The concave thread is preferred to a flat type because it will not twist at all when heated up. On the other hand, a concave-threaded bolt is very difficult to tighten or loosen because it contains two threads of different diameter. On the other hand, the convex thread is a little bit flexible and will expand slightly when heated. Thus, if you need an expansion type of bolt, the best option is a concave thread. These types of bolts are available in both metric and standard sizes and can be used in a large number of applications.
These are one of the most commonly used kinds of bolts around the world. However, it is important to make sure that you purchase your fixings from a reputable supplier who provides good quality products. Additionally, before you start using these threaded fasteners, you should learn about the proper installation procedures to ensure that you do not install the bolts in a way that leads to further damage or catastrophic failure of your machinery.
It is also important to keep the appropriate size tools with you when you start working on the project so that you can easily change the size of the nut if needed. Moreover, it is equally important to read and understand the instructions provided with the fixings so that you do not install the fix bolts in a way that causes damage to the equipment. In addition, if you have already installed several fix bolts, it is important to perform a comprehensive inspection of the system. By doing this, you will ensure that your equipment is running efficiently and so that you can work smoothly.
